PurposeResearch
ObjectivesThe objectives of this cruise were:
(1) Deploy current meter moorings at 57N, 9W and deploy moorings at two stations on the Rockall via Anton Dohrn Seamount section. Accomplished.
(2) Work the Rockall via Anton Dohrn Seamount (Ellett Line) CTD section. Accomplished.
(3) Work additional CTD sections in the northern Rockall Channel. Not attempted.
(4) Collect large-volume surface water sample for radiocaesium analysis from Scottish shelf stations. Accomplished with CTD profiles on all but one station.
(5) Obtain epibenthic sled samples at the SMBA permanent station (54° 40 min N, 12° 16 min W). Accomplished.
(6) Obtain deep plankton samples at the SMBA permanent section using the rectangular mid-water trawl. Accomplished.
(7) Obtain Assagiz trawl samples between the Anton Dohrn Seamount and the St Kilda continental slope. One good sample was obtained.
